to the controller.
4. Connect positive terminal (+) of battery to the battery positive terminal (+) on the
controller.
5. Connect negative terminal (-) of battery to one of the Common Negative terminals (-)
on the controller.
WARNING: Risk of Damage
Be sure that solar connection is made with correct polarity. Turn on the solar
breaker/disconnect and measure the voltage on the open wires BEFORE connecting to the
controller. Disconnect solar breaker/disconnect before wiring to the controller.
6. Connect positive wire (+) of solar module to the solar positive terminal (+) on the
controller.
7. Connect negative wire (-) of solar module to one of the Common Negative terminals
(-) on the controller.
8. Screw four (4) power terminals tightly with 50 in-lbs torque. (5.65 Nm)
3.5 Grounding and Ground Fault Interruption
Use a copper wire to connect the grounding terminal in the wiring box to earth ground.
The grounding terminal is identified by the ground symbol shown below that is
stamped into the wiring box just below the terminal:
The minimum size of the copper grounding wire is 8 AWG (10 mm2).
WARNING: Risk of Fire
DO NOT bond system electrical negative to earth ground at the controller.
3.6 Remote Temperature Sensor
The included Remote Temperature Sensor (RTS) is recommended for effective
temperature compensated charging. Connect the RTS to the 2-pole terminal (see
figure as below).
The RTS is supplied with 33 ft (10 m) of 22 AWG (0.34 mm2) cable.
There is no polarity, so either wire (+ or -) can be connected to either screw terminal.
